PAPER-CLAIVI P.

Speciiieation forming part of Letters Patent No. 52.403, dated February 6, 1866.

, To all whom it may concern:

Be it known that I, ADOLPH FABER, ofthe city of Washington, District of Columbia, have invented anew and Improved Clamp for Fastening Paper or other Material, and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making apart of this specieation, in which- Figure lis a side elevation. Fig. 2 is a section, A B. Fig. 3 is a perspective view, showing the clamp in actual use.

This clamp consists ot' a top plate, a, and bottom plate, b, or top plate alone, one or both of them being provided with any number of inclined or wedge-shaped surfaces, and also of the slides s, arranged so that by moving the slides s on the surfaces of the plates the top and bottom plate or top plate and inside surfaces of the slides (omitting the bottom plate or substituting` a thin slip of wood or pasteyboard therefor) will bebrought closer together,

and thus clamp the paper or other material by the movement of the slides upon the Wedges;

or, on the other hand, the paper or other material can be released by moving the slides s in an opposite direction.

The shape of the slides and plates may be varied to suit the fancy, and the slides may be secured to the plates by a dovetailed groove, or in any other Way, and the slides may be connected by small chains, or have rings attached by which the whole clamp can be suspended. One of the plates may also be enlarged or fastened permanently to a board or stiff pasteboard, so as to support the paper or other material.

Your petitioner does Ilot deny that clamps for fastening paper or other material have been previously devised; but

He claims- As a new and improved clamp, the combination of the open slides s, with. the inclined planes a and b, or a alone, substantially as alleged.
